Materials Data on CeSe2 by Materials Project
Abstract
CeSe2 is Low Tridymite-like structured and crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. there are four inequivalent Ce4+ sites. In the first Ce4+ site, Ce4+ is bonded to four Se2- atoms to form corner-sharing CeSe4 tetrahedra. All Ce–Se bond lengths are 2.73 Å. In the second Ce4+ site, Ce4+ is bonded to four Se2- atoms to form corner-sharing CeSe4 tetrahedra. There are three shorter (2.72 Å) and one longer (2.73 Å) Ce–Se bond lengths. In the third Ce4+ site, Ce4+ is bonded to four Se2- atoms to form corner-sharing CeSe4 tetrahedra. There are two shorter (2.71 Å) and two longer (2.72 Å) Ce–Se bond lengths. In the fourth Ce4+ site, Ce4+ is bonded to four Se2- atoms to form corner-sharing CeSe4 tetrahedra. There are one shorter (2.71 Å) and three longer (2.72 Å) Ce–Se bond lengths. There are ten inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a bent 150 degrees geometry to two Ce4+ atoms. In the second Se2- site, Se2- is bonded in a bent 150 degrees geometry to two equivalent Ce4+ atoms. In the third Se2- site, Se2- is bonded in a bent 150 degrees geometry to two Ce4+more »
